Rosa hybrid plant named ‘BBARE’

ABSTRACT

‘BBARE’ is a distinctive variety of  Rosa  hybrid which is characterized by the combination of a shrubby growth habit, a medium plant size, canes with few thorns, a recurrent bloom habit with moderate to strong bloom fragrance, a double-petal flower with a high petal count, a near-white flower color at anthesis, as well as the stability and uniformity of traits through successive cycles of asexual propagation.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Rosa hybrid.

Variety denomination: The inventive variety of Rosa hybrid disclosedherein has been given the variety denomination ‘BBARE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Rosa hybrid, shrubrose cultivar, which has been given the variety denomination of ‘BBARE’.

Parentage: The new Rosa hybrid cultivar ‘BBARE’ originated as anaturally occurring, partial-plant mutation of Rosa hybrid ‘Belinda'sDream’ (unpatented). Said mutation was initially discovered by theinventor in March of 2014 in a cultivated field of the parent plant atthe inventor's commercial nursery in Brenham, Tex. The inventor observedone cane of an individual ‘Belinda's Dream’ plant which was producingnear-white flowers instead of the characteristic medium pink flowers of‘Belinda's Dream’. At that time, three stem cuttings were taken from thecane that was producing the white flowers. The resulting plants wereisolated for further observation and to confirm uniformity and stabilityof the distinguishing characteristic. Subsequent cuttings were takenfrom these three plants which yielded a consistent crop ofwhite-blooming plants. The new cultivar was given the name ‘BBARE’ inNovember of 2014.

Asexual Reproduction: ‘BBARE’ was first asexually propagated byvegetative cuttings in March of 2014 at a commercial nursery in Brenham,Tex. under the control of the inventor and has since been vegetativelypropagated through one additional generation. The distinctivecharacteristics of the inventive ‘BBARE’ variety are stable fromgeneration to generation; plants of the variety produced by asexualreproduction maintain the distinguishing characteristics of the originalplant.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed andrepresent the distinguishing characteristics of the new Rosa hybridcultivar ‘BBARE’. These traits in combination distinguish ‘BBARE’ as anew and distinct cultivar.

-   -   1 Rosa hybrid ‘BBARE’ exhibits a shrubby growth habit; and    -   2. Rosa hybrid ‘BBARE’ exhibits a medium plant size; and    -   3. Rosa hybrid ‘BBARE’ exhibits canes with few thorns; and    -   4. Rosa hybrid ‘BBARE’ exhibits a recurrent bloom habit with        moderate to strong flower fragrance; and    -   5. Rosa hybrid ‘BBARE’ exhibits a double-type flower; and    -   6. Rosa hybrid ‘BBARE’ exhibits a near-white perianth color, at        anthesis.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinctvariety of Rosa hybrid known as ‘BBARE’, based upon observations of aplant, approximately 2 years old, grown outdoors, in full sun, at acommercial nursery in Brenham, Tex. Said plant was maintained withslow-release granular fertilizer and regularly watered with overheadirrigation. No artificial light, photoperiodic treatments, or chemicaltreatments were given to the plants. Observation data was recorded inNovember of 2014.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘BBARE’ hasnot been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such characteristics are approximations or averagesset forth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climactic and cultural conditions.

Plants of the new cultivar ‘BBARE’ are comparable to the parent varietyRosa hybrid ‘Belinda's Dream’ (unpatented) in all characteristics withthe exception of the flower color. ‘BBARE’ exhibits near-white flowersat anthesis whereas the parent exhibits medium-pink flowers at anthesis.

That which is claimed is:
 1. A new and distinct variety of Rosa hybridplant named ‘BBARE’, substantially as described and illustrated herein.
